“And one of the points I want to make is, is that if you actually took the number of Muslim Americans, we’d be one of the largest Muslim countries in the world,” Mr. Obama said. “And so there’s got to be a better dialogue and a better understanding between the two peoples.”…

United States: 2.3 million Muslims (according to the Pew Research Center).

“I think the most important thing I want to tell young people is that, regardless of your faith, those who build as opposed to those who destroy I think leave a lasting legacy, not only for themselves but also for their nations,” Mr. Obama said. “And the impulse towards destruction as opposed to how can we study science and mathematics and restore the incredible scientific and knowledge — the output that came about during centuries of Islamic culture.”…

You have the right facts, but I disagree with your interpretation. Obama’s math is correct. There are many predominately Muslim countries with fewer Muslims than the US. And yes, that scares bin Laden because he knows those American Muslims prefer Obama’s message of building to al Qaeda’s message of destruction. Bin Laden is concerned that the rest of the Muslim world may listen to Obama and agree.

Even a rational observer would note that being #41 on the list you provided is not one of the largest…not to mention the U.S. is not a Muslim country…but don’t worry 25+ years from now U.S. might crack the top 20

But by a similar logic Islam undoubtedly is THE largest perpetrator of terrorism with more than 13,300 acts of terrorism perpetrated by Muslims since 9/11 – click to review them all http://www.thereligionofpeace.com/
